Description
Interferon regulatory factor 1, also known as MAR is a protein that in humans is encoded by the IRF1 gene. The IRF1 gene is mapped to chromosome 5q31.1 by pulsed-field gel electrophoresis. IRF1 encodes interferon regulatory factor 1, a member of the interferon regulatory transcription factor (IRF) family. IRF1 serves as an activator of interferons alpha and beta transcription, and in mouse it has been shown to be required for double-stranded RNA induction of these genes. IRF1 also functions as a transcription activator of genes induced by interferons alpha, beta, and gamma. Further, IRF1 has been shown to play roles in regulating apoptosis and tumor-suppressoion
